Agronomic traits of banana diploid hybrids in three cycle of production in Cruz das Almas, Bahia

Objective this work was to evaluate agronomic traits of banana diploid hybrids, in three production cycles, seeking the selection of genotypes for use in banana breeding programs. Experiment was conducted between years 2005 and 2007, at complete randomized block in split plot design, with four replicates, in Cruz das Almas, Bahia, Brazil. Diploids hybrids 4279-06, TH03-01, 8987-01, 0323-03, 1318-01, 0116-01, 8694-20, 1304-06 and 9179-03, were evaluated regarding the characters plant height, pseudostem diameter, number of fresh leaves in flowering and harvest, pollen presence, bunch of training period, number of hands and fruits per bunch and fruit average mass. Hybrid 1304-06 showed the greatest in the three cycles studied, while the 0323-03 and 1318-01 showed intermediary port. Exception of 8987-01, 0323-03, 1304-06 and 9179-03, the other hybrids showed the number of leaves flowering more eight. At harvest, the 0323-03, 1318-01, 0116-01, 1304-06 and 9179-03, highlighted with the largest number of leaves. There is genetic variability among banana diploid hybrid studied. Hybrids 4279-06, 0323-03, 1318-01, 0116-01, 1304-06 and 9179-03, showed favourable agronomic traits and can be used as parents in banana genetic improvement programs.
